Invasives and highway departments
Isn't it time to study our worst weed pests? Not to only come up with effective IPM s, But, here's the hard part, get all HIGHWAY road crews to use these best methods? State and local?
Oh, and not use bad ones?
What about being willing to trespass to go the extra few feet, to keep bad invasives, at least managed. In an emergency, like the first appearance.
Some states have hotlines and websites, to report their worst invasives to their Agri. Colleges/Universities. They research the best ways [most effective and safest] to get rid of the pests. All states should have reporting sites. and share info with the next states.
Highway departments should then PAY ATTENTION to these best methods of dealing with invasives. Using these IPM methods for each noxious weed.
Phragmites, a swamp reed, was one of the earliest plants, the colonists brought, to help settle a 'new' continent.
It was used for thatch roofing. That other major plant intro was used for rope making. ...
We need to go all out on this one. This stuff is almost impossible to eradicate. Should we test the DNA? Maybe there will be clue there. Could it have hybridized with some, one, of the newly popular grasses? It's appearance and behavior have changed. It's gotten really aggressive.
Now it's growing on hills. Why, when it's a swamp plant? !
It's spreading readily along major highway roadsides,
The 'flower' inflorescences are purple, rather than green.
See pictures of huge efforts to get rid of it, on the recent weed post.
That darned giant smartweed/bamboo is blooming all over the place, cut the flowers off before it SEEDS. Lots of cutting will eradicate this one.
Those giant grapes, are escapees from nearby winerys, that have hybridized with our little 10 footers.
Asian bittersweet, russian olive, The lists go on. The northern states are lagging.
A more coordinated effort is needed.
